Answer:
The net chemical equation for the production of iron from carbon, oxygen and iron(III) oxide:

Explanation:
Step 1: Carbon and oxygen react to form carbon monoxide:
..[1]
Step 2: Iron(III) oxide and carbon monoxide react to form iron and carbon dioxide:
..[2]
The net chemical equation for the production of iron from carbon, oxygen and iron(III) oxide can be obtained by :
3 × [1] + 2 × [2]

CO gas will gas cancel out form both sides ans we will get the net chemical equation:

According to reaction, 2 moles of ferric oxide reacts with 6 moles of carbon and 3 moles of oxygen gas to give 4 moles of iron and 6 moles pf carbon dioxide gas.

Answer: 4.72 × 10⁷ s⁻¹ or Hz</h2><h3>
Explanation: </h3>
frequency = speed of light ÷ wavelength
frequency = (2.99 × 10⁸ m/s) ÷ (6.34 × 10⁸ m)
= 4.72 × 10⁷ s⁻¹ or Hz
